Abstract: A polyolefin composition includes: a) ≥65.0 wt. % and ≤94.0 wt. % of an ethylene alpha-olefin co-polymer (A); and b) ≥6.0 wt. % and ≤35.0 wt. % of an ethylene polymer (B). A foamed article contains such a polyolefin composition. The foamed article is obtained by compression foaming a foamable polyolefin composition or a foamable thermoplastic polymer composition. The foamed article can be used for improving the fatigue resistance and mechanical properties of midsole used in a footwear.
